1 '0 all whom it may concern:

Be it known that I, Lnwrs E. WATERMAN, a citizen of the United States,residing at Rockford, in the county of Winnebago and State of Illinois,have invented certain new and useful Improvements in Two-Way Plows, ofwhich the following is a specification.

This invention relates in general to plows, and particularly toreversible or two-way plows adapted for hillside plowing. Morespecifically, the invention relates to the class of two-way plows havingbails on which the plow beams and carrying wheels are mounted and whichare operated either manually by hand levers or by power from thecarrying wheels to raise the plows. By reason of the fact that thecarrying wheels are customarily mounted on fixed axes on the bails thewheels are maintained in fixed vertical relation with respect to theframe whether in raised or lowered position. The result of such aconstruction is that the carrying wheel traveling in the furrow can noteffectively resist the side thrust of the plow, consequently, unevenstrains on the bearing of the furrow wheel and an increase in the draftresult. Furthermore, the wheel treads in the furrow in so nearly anupright position as to strike against and tear down the side wall.thereof, thus clogging the wheel, increasing the draft and causing thewheel to frequently run out of the furrow, all of these undesirablefeatures being accentuated in proportion to inclination of the hill-sidebeing plowed.

My invention aims, primarily, to overcome these objectionable featuresand to this end I have devised a two-way plow in which the carryingwheels may be tilted laterally relatively and with respect to the frameso as to most efliciently serve their purpose as carrying members and toeffectively resist the side thrust of the plows, thus materiallydecreasing the draft.

More particularly, I have provided twoway plow in which each carryingwheel and its adjacent plow may be raised and lowered in unison and thecarrying wheels will be automatically canted laterally during suchmovement so that when the plow is raised the wheel will tread in avertical position relatively to the frame and when the plow is loweredthe wheel will tread in an inclined position in its furrow, cantedoutwardly with respect to the vertical axis of the frame.

Other objects and attendant advantages will be apparent as the inventionbecomes better understood by reference to the fol. lowing descriptionwhen considered in connection with the accompanying drawings, in whichFigure 1 is a side elevation'of a two-way plow embodying myimprovements, showing the left hand moldboard in working position;

Fig. 2 is a side elevation of the plow showing the right hand moldboardin raised position;

Fig. 3 is a plan view of the plow; and

Fig. 1 is a rear View thereof.

The frame of my improved plow is of comparatively simple designconsisting of a cross beam 6 having rearwardly turned ends 7 an angleiron beam 8 positioned above the beam 6 and segment brackets designatedgenerally by reference character 9 to which the ends of the cross beamsare bolted. A pair of plow' carrying bails 11 are pivotally mounted attheir inner ends on a common pivot bolt l2carried by rearwardlyprojecting supporting plates 13 bolted to the cross beam 6 and arepivotally mounted at their outer ends on pivot bolts concentric with thebolts 12. It will be, noted that'each bail is formed in two parts, theouter arm 15 being a separate part. This arm at its free end is providedwith a sleeve 16 through which the forwardly turned outer end 17 of themain part of the bail projects longitudinally of the machine. A setscrew 18 secures the arm 17 fixedly to the sleeve 16 so that-the bail isin efi'ect an integral structure. Each bail carries a suitable plow beam19 equipped with amoldboard. A drivers seat may be mounted on the frame.A tongue 21 is suitably connected to the frame, and as is well under-vstood in the art means, not shown in the present instance, may beprovided for adjusting or swinging the tongue laterally with respect tothe frame to take care of the side draft of the implement when plowingon difierent grades. 7

Upon the arm 17 of each bail is pivotally mounted a yoked bracket 22carrying an axle 23 secured rigidly thereto, and on each axle isjournaled and suitably secured a carrying wheel 24 equipped at its innerend with a toothed ratchet wheel 25. By reason of this construction,each carrying wheel and its plow beam may be raised and lowered withrespect to the frame by simply swinging the bail on its pivots and theswung backwardly and forwardly by hand in the usual manner to rock thebail and at the same time a lateral tilting movement is imparted tothe'lever by the cooperating segment which is mounted at an angle to thelongitudinal aXis of the machine.

The segment 9 having a toothed underface 26 is shaped to extendoutwardly and rearwardly from the cross-beam, thus providing a laterallyinclined cam way 27. The hand lever 28 fixed to a bracket 29 in turnrigidly secured or formed integrally with the yoked part 22 is equippedintermediate its ends with an inwardly extending bracket 31 that carriesa pair of cone shaped rollers 32 arranged to engage the inner and outersides of the segment 9 so as to slidably associate the hand lever withthe segment and maintain the lever in fixed relation thereto at all.times. Thus when the lever 28 is swung back and forth on the pivot aXisof the bail to raise and lower its plow, it is also tilted laterally dueto the lateral inclination of the segment, this lateral tilting movementof the lever being independent of the bail on the axis of the arm 1'?thereof. Since the lever 23 is in effect integral with the axle. 23, thelatter will also be moved about the axis of the arm 17. The effect ofthis construction is to cant or tilt the carrying wheel from a verticalto an outwardly inclined position such as is shown at the left of Fig. 4when the hand lever is moved from its foremost to its rearmost positionto lower the plow into the ground.

Means are provided for locking the hand lever to the segment and foroperating the lever by power to raise its plow to inoperative position.This means'comprises a dog carrier 33 embracing and slidably mounted onthe lever 28 and equipped on its inner side with an integral dog 34adapted to engage, the notched face 26 of the segment. An expansionspring 35 operating between the parts 33 and 29 constantly urges the dog34'toward the notched face A dog 36 slidable in a guideway 37 integralwith the bracket 29 and connected at 38 to the carrier 33 is adapted tobe moved into and out of engagement with the ratchet wheel 25 bymovement ofsaid carrier 33 longitudinally on the lever. The dogs 34 and36 are so were relatively arranged that when the dog 34 is engaged inthe face 26, the dog 36 will be disengaged from the ratchet wheel and sothat the dog 34 may be moved out of engagement before the dog 36 ismoved. into engagement with its respective toothed face. The dog carrier33 normally urged into locking connection with the segment 9 by means ofthe spring 35 may be operated by a hand lever 39 to withdraw the dogfrom its segment. For this purpose the hand lever 39 mounted on thelever 28 and connected to the slide member 33 through means of a link 41may be moved in a counterclockwise direction viewing Fig. 1. A secondlever 42 mounted on the lever 28 is provided for moving the dog carrier33 farther downwardly to engage the dog 36 with the ratchet wheel. Thelever 42 is connected to the slide member- 33 through means of a link 43and it will. be noted that this further downward movement by the lever42 does not affect the lever 39 because of the slot connection betweenthe latter and the link 41. The lever 42 may also be operated by meansof a foot lever 44 pivoted at 45 to a depending extension of the segment9 and having its outer end connected at 46 to a link 47 which isconnected at.43 to the lever 4. By means of the foregoing operatingmechanism the operator may cause the plow to be raised from the groundby power either by pressing forwardly on the foot lever 44 or byoperating the hand lever 42, which operation as already explained willdisconnect the lever 28 from the segment and engage the dog 36 with theratchet wheel, causing the plow to be lifted by the rotation of saidwheel. When the plow is elevated to a predetermined position, the dog 36will. be automatically disengaged from the ratchet wheel andsimultaneously the dog 34 will be moved into engagement with the notchedface of the segment thereby locking the plow in raised position. Thisresult is effected by means of a roller 49 mounted on the upper end ofthe dog carrier 33, which roller engages and is operated by an inclinedcam 51 disposed forwardly on the peripheral face of the seg ment 9, itbeing obvious that as the lever is swung to its foremost position theroller 49 will be moved up the incline 51 and opera ate the dog carrier33 for the purpose described.

lt will be understood that the plow and wheel carrying and operatingmechanism at each-side of the frame is identical in construction andoperation and that when plowing on a side hill the plows are usedalternately in plowing back and forth. For instance, with the left handplow in operation the plow is raised at the end of the furrow, theimplement turned about and the right hand plow lowered into the groundto turn up the next new land. In plowing in this manner with my improvedplow, it will be apparent that when either plow is raised or lowered itscarrying wheel is simultaneously and automatically angled or tiltedlaterally to a desired and most effective working position. With theleft hand plow in the ground its adjacent wheel assumes the laterallyinclined position shown in .Fig. 4c, in which it will be noted that thewheel treads in the corner ofthe furrow and is in no way liable to teardown the edges-of the furrow wall and to become clogged with dirtthereby. Furthermore, the carrying wheel when treading in this mannerserves to most effectively carryand resist the side strain or thrust ofthe plow. In this connection it will be noted that the axle bearingbecause of its inclined position and of the direct manner in which theside strain carried by the wheel, is not subject to the severe unevenwearing strain which theaxle of a furrow wheel in upright position wouldreceive. These features all promote lightness of draft since the plow iscarried and guided in most eilicient manner and they in no way impedethe plowing or present abnormal wearing or working conditions. While Ihave utilized the segment bracket to effect lateral movement of thecarrying wheels, it should be understood that I do not limit myself tothis particular method for accomplishing the objects desired sincevarious other means might be employed for the same purpose. changesmight be made without departing from the spirit and scope of theinvention or sacrificing any of its material advantages.
